The proposed system yields fast capacitor loss measurement with high accuracy in a real circuit. The capacitor loss can be analysis for each switching period of power electronics converters. The impact of capacitor loss through the implementation of a PWM technique can be analyzed.
Capacitor loss under power electronic converter excitation can be measured using the calorimetric method [ 4, 5 ]. In this method, the loss is measured from temperature rise in the chamber. Therefore, an insulation between the chamber and the outside air is required to improve the loss measurement accuracy.
A capacitor loss analyzer system used for power electronics converters is presented. The capacitor loss of a filter capacitor in a single-phase PWM inverter is analyzed, and the measurement accuracy is verified by comparing the measured values and the calculated values.
